Don’t you love it when a judge mulls over two competing accident reconstruction reports, selects what he thinks is most probable, and then finds as a fact that that is how the accident happened….grrrrr.Welcome to the fantasy land of the balance of probabilities.

A welcome return to reality was made in Lambert v Clayton which unhelpfully is tucked away in that much unread series the Road Traffic Reports. [2010] RTR 3.The parties had accepted the judge’s findings of fact for the purposes of the appeal. But in a powerful obiter dictum, Lady Justice Smith made it clear that, in general, precise findings of fact may be wholly unwarranted, particularly where there is a range of speeds, stopping distances and reaction times.On one version of the reconstruction, the speeding motorcyclist was there to be seen, on another he was not.It was not for the judge to decide which one was correct “if there are inherent uncertainties about the facts…This may well mean that the party who bears the burden of proof is in difficulties….”.

As far as power allocations, usages and distributions, one should take into consideration the importance of proper groundings. In any particular hospital wing or building, a common power ground as well as a common signal ground must be established and together which must be tied together into a common point in that building to avoid any ground loops. By doing so, ground impedance and/or resistances can be brought to a minimum, thus eliminating any difference in ground potentials, minimizing any noise /harmonics in the power lines that eventually will interfere with the proper operation of any medical equipment.
